Bi-Plane

This is a modified version of the excellent 'Little Puzzle Plane' designed by shiung0202 first published in June 2017.
I decided to design a version that was more robust and able stand up to my two young grandsons trying to fly and throw the plane at the wall! So I stiffened and made all parts thicker.
Rather than press parts together I used epoxy glue for all joints and then assembled the plane. The result is the plane is more solid and has been able to stand up to some rough treatment.
The parts can be printed flat, 50% infill and no supports
Have fun and hope you enjoy it
